scope:
This Standard establishes specifications for the execution of tension tests to be carried out on an anchor grouted in the ground, as defined in EN 1997-1 and EN 1537. Three methods of test are recognised by this Standard. Method 1 involves cyclic tension loading with measurement of displacement at the load stages. Method 2 involves cyclic tension loading with measurement of loss of load after lock-off at peak load and Method 3 involves step-loading with measurement of displacement under successive maintained tension loads. The standard provides specifications for three types of tension tests as defined in EN 1997-1 and EN 1537: investigation tests, suitability tests and acceptance tests. The standard provides specifications for the experimental devices, the measurement apparatus, the test procedures, the definition and the presentation of the test results and the content of records.
